It is an instrument used to measure blood pressure.
Answer:
option C
multiplication factor n = 1 when volume change to half and pressure become double
Explanation:
we know by Ideal Gas law:
P1V1 = nRT1
P2V2 = nRT2
according to the question
pressure is doubled and volume is reduced to half
so we have
new pressure = 2*P1
new volume = V1/2
hence,
(2P1) * (V1/2) = nRT2
P1V1 = nRT2
we have now
nRT1 = nRT2
we get
T1 = T2
thus no change in temperature
we know that internal energy is given as
internal energy = nCvT,
since temperature is directly proportional to internal energy and since temperature remains constant therefore internal energy remains constant
So there is no change in internal energy
thus, multiplication factor n = 1 when volume change to half and pressure change to double

because your hair is a mixture of your dad and mom and their dads and moms
its not like you only get your moms genes or only your dads genes
so its a mixture

The sun crosses the plane of Earth's equator when the center of
the sun coincides with either of the two points on the map of the
sky labeled "equinox".
One of the following two phenomena occurs at that time, depending
on the direction in which the sun crosses the plane.
1). People all over the northern hemisphere shout and exclaim "It's Spring!",
whereas those in the southern hemisphere yell "It's autumn now.".
2). People all over the northern hemisphere yell "It's Autumn now.", whereas
those in the southern hemisphere shout and exclaim "It's Spring !".
Well you’d have a force due to gravity, the normal force which will be perpendicular to the sources (meaning you’ll have components to this vector), and you’d have the force of friction opposing the motion of the box. I’m also assuming there’s no air resistance. In this case you’d have three vector forces.
